Coming up, food prices are starting to rise as the Middle East conflict chokes fertilizer supply.

And OpenAI is designing a desktop super app with hopes of muscling out Anthropic.

We'll also check in with Carl to get his answers to your burning questions.

More on the way, but first, a word from Guy at Finimize HQ.

Food prices are beginning to climb as hostilities in the Middle East send shockwaves through global supply chains and increasingly into the cost of fertilizer.

Food production is more than just planting seeds and watching crops grow.

Every meal is the product of a global web of input, energy, and logistics.

And right now, conflict in the Middle East is exposing just how fragile that web is.

The Gulf region is a major producer of urea, a key nitrogen fertilizer that's needed to grow food at scale, made in chemical plants from natural gas.

And the Strait of Hormuz is the area's main shipping channel, so any disruption there keeps all-important urea from reaching global buyers.

It makes sense, then, that urea's price has leapt about 30% in the past month.

Unsurprisingly, that's stoked fears of a more sustained food production cost increase and sent prices climbing.

Case in point, the cost of corn, a cornerstone U.S.

crop used in everything from livestock feed to biofuels, has shot up 10% over the past month.

Higher food prices tend to hit emerging economies the hardest, as food there makes up a bigger share of household spending.
